Copper diphosphine complexes have been found to be highly active and selective homogeneous catalysts for the hydrosilylation of CO 2 . The structure of the phosphine ligands strongly affects their catalytic activity. Turnover number (TON) reaches 70 000 after 24 hours with 1,2‐bis(diisopropylphosphino)benzene as a ligand under 1 atmosphere of CO 2 . 1 H and 13 C NMR spectra, carried out under the reaction conditions, showed the reaction mechanism through insertion of CO 2 into CuH to afford Cu/formate species.
